'Seven million' O2 users affected

Around a third of O2 customers, about seven million people, were "potentially impacted" by its network outage, the mobile service provider has said. The networks have been restored after users were unable to send or receive calls or texts.

That is roughly 7.6 million of the mobile service provider's 23 million customers.

He also said: "We absolutely want to make it up to our customers for the service that didn't get, the key for us now is to underpin the reliability of the service and restore our customers' confidence."

O2 mobile network provider have said that their "tests" show that both 2G and 3G services have been fully restored for all affected customers. Thousands of users were left unable to send or receive calls or texts after the network crashed yesterday.

The Guardian have reported that the Mayor of London's popular fleet of rental bikes has become the unexpected victim of network provider O2's service failure yesterday, as more than 100 bike stations across London were hit by a network blackout.

Almost one in five of the capital's bike terminals were out of commission for pay-as-you-go customers because they use the O2 network to process card payments from customers.

Transport for London, which operates the Barclays Cycle Hire scheme, said its bike terminals use O2's 2G network to process debit and credit card payments from the terminals. Those who are after a one-off ride on a pay-as-you-go basis, are thought to have been affected by the Boris bikes blackout.

"We want to see O2 offer compensation to all customers who have been hugely inconvenienced by this service blackout and have been paying for a service they cannot use. People should also keep a log of any costs they incur to help with any claims for compensation."
